This cool tool has become an all-day companion for me.
I would consider to donate, but how?

Great piece of software. Can't imagne the internet without it.

OMG! the freaking ad in my email inbox was bugging the crap out of me. i had another blocker that only took care of the ads on the side of the page, but not the ad in my inbox. THIS ONE TOOK CARE OF IT FOR ME! THANK YOU!

Good

Best Ad Blocker EVER

My favorites extension

Brilliant! I use the medium level of blocking, took me a while to get the hang of it, there is a very good video online by the 'disliked' one, who takes you through the different levels.
Wouldn't be without it, the more you get into it, the better it gets.
Update: six months on from deciding to go into medium/hard modes, it has been worth the time and effort. I now have a relly good understnding of being able to 'read' websites and know what needs to be done, in terms of the settings.

It's defintely worth the effort to get to grips with uBO.
